DOUGH-CONTAINER FOR BAKING I-IERTH-BREAD IN AUTOMATIC OVENS.

LIISLS.

Application filed January 14, 1915. Serial No. 2,1323;

To all 'Lc/1 om it may conce/ra Be it known that I, Huso GoT'rscHALK, a citizen of the United States, residing at Burnham, in the county ot' Mifflin, State of Pennsylvania, have invented a new and useful l)ough-(rlontain'er for Baking Hearth- Bread in Automatic Ovens, of which the following is a specification.

My invention relates to a new and useful dough container for baking bread in an automatic oven and consists of a foraminous support for the bread, by means of which, `when the loaiI is carried into the oven substantially the entire outer surface thereof will be subjected to the same heat and vapor conditions in the oven, and when"the support is deposited Vdirectly upon the hearth, the bottom of the loaf will be substantially in contact with the hearth.

It further consists of other novel'features of construction, all as will be hereinafter set forth.

For the purpose of illustrating my invention. I have shown in the accompanying drawings one form thereof which is-at presgive in lpractice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously'arrarfged andorganized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a vertical section on i line .Q2-m Fig. 2 of an .automatic oven, showing my novel container in operative posi'- tion.' Fig. 2 represents an end elevation of the same. Fig. 3 represents. an enlarged detail of the receiving end ot' the oven. Fig. 4 represents ar top plan view of a container embodying my invention. Fig. 5 represents a sectional view on line jz/e-'fl/ Fig. 4, on an enlarged scale.

Similar lnumerals of reference indicate corresponding parts in the figures.

Referring to the drawings :-It will be understood that the dough container is more particularly adapted for baking vso-called hearth bread, and is to be used in connection with an automatic oven of any suitable construction, wherein the containers or supports are carried into the oven, deposited `upon the hearth, during the baking. operal Specification of Letters Patent.

A each of the lower frames 2 is a foraminous supporting means which forms the sup;-v port proper for the bread or loaves, and which is formed of anysuitable material,

such as netting, wire mesh, or other porous I material. The :toraminous supports may be connected-with their respective'frames1in.

any suitable or desired manner'. Above thel supports 4, here shown as connecting the ,frames l, are bars or straps 5, which are thus positioned at a. suitable distance above the supports 4, and which latter are spaced apart to provide sufiicient clearance for the passageof the ychain conveyers of the oven in order that the said straps or bars may rest on the chains, whereby the containers may be carried into and through the oven.

vThe bars are provided with means adapted for interlocking engagement withV coacting means on the conveyer,- and, asv here shown, the bars are provided with suitably spaced vopenings for this lpurpose.

In the present instance, three foramlnous supports spaced from each I have shown other and carried by theframes l suitably connected, the Awhole forming a unit in op eration and use, but any number. of supportsmay be employed and differently arranged 'as is desirable andadvantageous.

In the support or container illustratedI have shown the saine as adapted for usein an automatic oven similar to that disclosed In the oven illustrated, 6 designates the wallA of the oven formed of any suitable material and which is provided with a longi# tudinally'arranged oven chamber 7. This chamber 7 is preferably in communication with one end. of a mixing room of a bakery while at the other end, it is in communication with the bread room, suitablev openings 8 and 9 being'provided for this. purpose and controlled by suitable doors 1.0.

11 designates the oven floor or hearth,

A which is-liere shown as formed with an .in-

clined Way 12st each end in order to confine and prevent the escape of heat when one or the other of the doors are opened. Longitudinally disposed of the hearth 11 is a pair of channels `13 which extend a suit able distance below the iioor of the ove`n to receive the supports or beams -14 for a vconveyer mechanism, which will be hereinafter described. j v a .In my preferred construction, there is one beam 14 located in eachlchannel 13 and pref-H erably projecting therefrom at each end in order to seat upon a movable support independently of walls 6.

As here shown, the ends of the respective. beams 14 are carried by a pistoni-od 15 hav-- ing its'- piston or plunger. 16 :slidingly mounted within a Xed cylinder 17. The cylinders 17 are connected to and have communication at or 'near the bottom-withfa pressure fluid lin'e orpipe 18, control of which is had by means of the valve 19. This valve 19 is preferably of the three-way type to exhaust the line at certain times and is located adjacent theinlet opening 8 or feeding end of the oven and in a position convenient for ready operation. When the valve 19 is open pressure `fluid from a suitable source is simultaneously admitted beneath all of the pistons 16 consequently movingy the rods and thereby raising the beams 1.4, so that the conveyer mechanism may be brought above the floor of the oven.

20 designates suitable posts or standards .j

secured to each beam 14 at certain intervals and preferably of such lengths as to cause the conveyer 21, here shown as chains, to.

closely follow the contour of the hearth or ovenloor. It will lbe noted that each. standard 2O serves as a journal support for the sprockets 22 which carry the conveyer chains 2l, and prevent sagging intermediate the ends thereof. l Each standard 20 is also provided with an idler,23 for thereturn por-v 29 designates the driving-sprocket which.

receives power from the belt 30 or equivalent means. l l

31 designates a feed table positioned adjacent the inlet opening 8 and preferably having its supporting surface .formed by transversely disposed rolls 32, the spindle ci" axes of which lie in an inclined plane substantially :in alinement with the inclined hearth or oven surface 12, and around said rollers is a belt 33 for carrying the containers. 'A second table of similar construction is located adjacent the discharge end of the oven as shown `at 34. j

. As will be understood, the containers or supports for the loaves are suitably spaced apart to provide for sufficient clearance be'- tween adjacent supports tov pass `the conveyer chains 21 and to allow the bars 5 to 'rest u'pon the said chains with the openings of said bars in engagement with the projecting means 35'of the chains in order that y there will b e an interlockingengagement of the chains Witheach container or plurality of' supports, by reason of which the containers are positively held in line and in proper position to be directed through the oven without fear of bein displaced upon 'the conveyers `tocatch or jam in the oven,

and in addition, as the containers are re-l leased from the discharge end of .the confveyers and directed upon a discharge table or other support, each succeeding container acts Yas a means to push the preceding containers from their position adjacent the said discharge end of the containers.

36A designates a belt shift for bringing the this forms no part of my invention.

The operation of the oven is as follows -The conveyer mechanism is first started by shifting the belt 30 or like driving means.

The -filled supports are then placed upon .the table 31 and pushedinto engaging relation with the conveyer chains, it being noted that the inclinationis such" as to correctly position the supports relative to the conveyer. As fast as one set of supports is carried forwardinto the oven, another set fols lows until the capacity of the' oven is reached. When 'this occurs, the` operator shifts the driving means tobring the conveyer to rest, in which position the supports are suspended above the hearth or oveniloor and not in contact therewith. foregoing operation, pressure Huid is acting on the pistons 16, thus holding'the conveyer mechanism in raised position. The operator now cuts off the supply of pressure fluid and allows the cylinders 17 to exhaust gradually through the valve 19, whereupon the conveyer mechanism .is gently lowered by grav ity until the supports rest directly upon the oven loorl This position makes possible` baking of the dough in the coiiect,inannei'..

since theA heat acts first on the bottom of the las granato loat and worlis invward through vthe dough as it should tor the best results. lv'hen this baking is completed. -)rL-ssure fluid is again admitted to the cylinders l? to remove the supports from contact relation with the, oven lioor, the eonveyer is again started and as one set ot' supports is removed at the discharge end. another set containing fresh dough is ted in. at the receiving end. ln this manner. the supports are continuously lied into the oven. baked and removed therefrom while the mixingr room is maintained separate and distinct trom'the bread room` thus avoiding contusion and eliminating' a large number oi skilled employees.

ln order to prevent as'tar as possible a draft through the oven when being charged. l preferably provide a suspended baille 3b of asbestos or like material adjacent the discharge end o'lr the oven am. which Vforms substantially a partition between the main oven portion and the exit end. ly this construction a large amount ol' heat and heated vapor, otherwise wasted. is saved.v

lt will now be apparent that l have devised a complete unitary structure particularly adapted ior the purpose intended and embodying a simple and el'l'ective.construction to the desired end.

ly forming the support or bottom ot the container of relatively very thin material. which is toraminous or porous. it will provide that when the support is deposited upon the hearth` substantially the entire bottom oiE the loaf will be subjected to the direct heat ol the hearth, b v means ot which l am enabled to produce the so-called hearth goods. lleretotore. in the nninulacture oly the so-called hearth goods. it has been cus'- toniary to place the loaves lon clot-h or in boxes and thereafter place them upon a peel. by which means they are inserted into an oven. ly the use' ojt the present container. as soon as the loa l is made up or Al'ormed. i' can be placed directly upon the i'oraminons support and not removed. tliereironi until the baking is completed. lxtra handling of the loaves is thus avoided and it further insures that the loaves will be held in proper position without tear oi" striking each other, thus avoiding the formation otI so-called "cripples" which arise in many instances, whereI the peel is ennpiloyed, by the loaf sticking thereto or by one lont being shoved against`another. Another advantage derived irom lthe use. ot the toraminons snpport is that substantially the entire outer surface.` ot the loa't will. be simultaneously subjected to substantially the same vapor and heat conditions when inserted in the oven, which is impossible when the ordinary methods are employed.

it will be further understood that by providing skeleton `traine for the supports, the heat and vapor can evenly circulate around the loal. to subject the entire outer sur'l'ace thereoit to the proper baking action, but it will be understood that any suitable construction may be employed to accomplish this result and which will suitably carry the supports.

lt will now be apparent that I have devised a novel and useful dough container lor baking' hearth bread in automatic ovens, which embodies the t'eatnres .of advantage enumerated as desirable in the statement ot' the invention and the above description, and while l ha ve. in the present instance. shown and described a preterred embodiment thereo,i which will `'ive in practice satisfactory and reliable results. it is to bennderstood that the same is susceptible of modilication in various particulars. without departing l'i-om the spirit or scope ot' the invention or sacrilicing any ol its advantages.
